Fermented White Rose Extract | Skin Brightening Active

Overview. The white rose Rosa Damascena 'Nuan Yu' is a rare, pale-bloomed damask rose variety whose flowers combine the legendary aromatic elegance of damask rose with a gentle, luminous profile. YaoSynBio YS-015 is produced by red-yeast fermentation of fresh white rose flowers: rather than a simple distillate, the process bio-transforms the entire floral matrix, yielding a clear pale yellow liquid (pH 4.0–5.5) that captures the flower's polyphenols, amino acids and lipid fractions in an activated, skin-ready form.

Mechanism. Red-yeast enzyme hydrolysis during fermentation dramatically upgrades the extract's active profile — flavonoid content increases by 34.1% and polyphenol content by 76.1% — providing strong antioxidant defense against oxidative dullness and premature aging. The fermented essence is naturally rich in over 70 amino acids, which support hydration and skin resilience, and more than 50 unsaturated fatty acids, which help nourish and reinforce the lipid barrier. Together these components brighten and even the complexion, lock in moisture, and leave the skin soft, smooth and radiant.

Applications. Recommended at 2.0%–5.0%, YS-015 is ideal for brightening serums and essences, moisturizing toners and lotions, antioxidant day care, and luxury floral / aromatherapy-positioned skin care. Its pale, crystal-clear appearance and elegant ingredient story suit both high-end essences and sensorial "flower fermentation" ranges, with full cosmetic compliance in the EU (CosIng, EC 1223/2009) and the US.
